A college wants to determine if the grade in a Physlcs higher if they make Calculus 1 a perquisite instead of a corequisite. The college randomly samples 100 students that completed a Physics 1 course that took Calculus 1 as a prerequisite. The average grade of these students was a 76% in their Physics 1 course, with a standard deviation of 20%. The school randomly sampled 140 students that completed a Physics 1 course that took Calculus 1 as a corequisite. The average grade of these students was a 74% with a standard deviation of 21%. Defining population 1 as the students who took Calculus 1 before Physics 1, and population 2 as students who took Calculus 1 with physics, use a 5% significaice level to determine if the average grade of all students who take Calculus 1 before Physics 1 is higher. Give the hypotheses. Null: There is no difference in average grade. Alternative: Students who take Calculus 1 before Physics 1 will have an average higher grade. Null: There is no difference in average grade. Alternative: Students who take Calculus 1 with Physics 1 will have an average higher grade.
